It's nothing major, she just needs to have her tear ducts unblocked. Apparently 30 mins in all, 10 mins to put her to sleep, 5-10 mins to do the procedure and another 10 mins to get her fully awake.
I am of the 'forewarned is forarmed' school of thought so if anyone can please tell me what to expect I'd be very grateful (I think).
TIA
